Wifi in client mode is certainly broken. On newIt's forum, there's a thread named "My guruplug has no problems and is working", guess what? With one exception, each and every post out there mention that wifi and bluetooth are disabled.

Seems the only hope is in a better libertas driver. We'll have to beg Marvell or a some dedicated developper for that.

I can certainly confirm that the Guruplug will not work for very long as a WiFi client with the factory distribution. I have also tried recompliling using the sources published with no difference.

I created a really simple script. I have two Guruplugs and the same happens on both. When I run this on a Guruplug connected ONLY via wifi to my home router, the Guruplug crashes - typically after 1 - 2 minutes. There is no error when using ethernet of course!

The same error occurs when using curl to download instead of wget (so it is not the wget package), but it works when I copy the file from one directory to another (ie eliminating the wifi element of the test).
